Front-end translation for user interactivity.

[Dwctor]

Currently Honey-Potion creates a generic Front-end using LIBBPF to open, load and attach the program skeleton. Other than that, the Front-end can change when there is a map to be printed, allowing the output of it's values.

An improvement to that behavior would be to allow users to define their own Front-ends in a Elixir function that then gets translated for them. That way, we can eventually allow user interactivity in our program. For example:

def frontend() do
    Front.getinput(char)
    case char do
         "a" -> BPF.open_load_attach("Program_a")
         "b" -> BPF.open_load_attach("Program_b")
         x -> Front.print("Usage: <char> where char is "a" or "b"
    end
end

Other than getting a user input, we could also get command line arguments.
